Although dollar's rebound after falling to a multi-year low yesterday at 99.77 suggests initial consolidation above there would be seen, reckon upside would be capped below 101.60/70 and yield retreat later.  
Below intra-day support at 100.30 (Australian low) would signal downtrend has possibly resumed and break of 100.00/02 would confirm, bring re-test of said support and then 99.50.
